There are a number of clinics in the city but at Joppa health methadone clinics, people who are experiencing opioid use disorder in the city or nearby places would get medical assistance to overcome the problem. Methadone clinics dispense medication and provide psychosocial support for the correction of opioid dependency. Methadone is a safe opioid agonist approved by the Food and Drug Administration. Its effectiveness has given it a place on the World Health Organization’s list of essential medications. Methadone blunts the adverse effects of opioids. It helps patients function better socially. All methadone clinics in Maryland are required to be accredited by the Substance Abuse and Mental Health Services Administration before commencing the opioid treatment program. Doses of methadone are tailored. They are not to be shared between individuals because patients are given the exact doses needed at a time. For the first few days of maintenance, the patient has to stay under the close observation of the medication-assisted treatment practitioner who monitors their responses to treatment and adjusts the doses accordingly.
